Original No. 1,397,844, dated November 22. 1921, Serial No. 382,848; flied May 20, 1920. Appllcatton m reissue filed October 25, 1923. Serial No. 670,799.

This invention relates to heel shaping machines and is disclosed in connection with a machine for turning wood heels.

In wood heel turning machinery ordinarily constructed, the WOI'h'. holder or jack is rotated before the cutter by a handle grasped by the operator. The work is clamped in the jack bya clamping mechanism Whieh is tightened and loosened by the operator at he inserts or removes a heel blank, by means of a manually operated member. The operation of this member in handling a blank requires several movements of the hand which then has to he moved to the jack operating handle (or this order of movements may he reversed). In any event, the numerous movements required consume much time.

it an object of the present invention to avoid the necessity of so many movements on the part of the operator, with the accompanying: loss of time. To this end in accordance with a principal feature of the. invention. as herein illustrated. the clamping handle of the jack is arranged to he used as the main operating handle by which the jack is swung to out a heel. Thus the operator does not have to shift his hand from the operating handle to the clanming merino nism, or vice versa, and is enabled to save IDlCll time as compared with heretofore known machines.

It has been found in machines ot this character that there is a tendency to lift, the block holder (ltll'ltlg the cutting operation and thus make defective heels and it one of the objects of this invention to over (time that ditiiculty. Awordingllt'. a spring is provided to hold the hlock holder down in proper position.

These and other features of the inrention will he apparent from the tollowin; description of an illustrative einhodinirnt of the invention read in Lainnection with the appended drawings.

Referring to the drawings:

In the drawings. 15 is the frame of the heel turning; machine, 16 and 17 are the cnt- 7o ters which are fast to vertical rotary shafts l8 and t9 respeetiwly. said shafts being rotatahly mounted in hearings on the frame of the machine. 20 is a vertical shaft llJOIl which is rotatahly mounted an arm 21. lhe (5 arm 21 is provided with bearings 22 and 23 in which slidahly and rotatably mounted a shaft 24. The shaft 24 has a collar 25 fastened thereto and between this collar and the lower end of the hearing 22 said 0 shaft 24. i encirrled by a spring 26, the tendeney of said spring being to hold the shaft 24 downwardly. To the lower end of the shaft 24 fastened an arm 27 and jonrnaled to said arm is a long roll 28 which 55 is :ulapted. when the blank holding mechanism or jack being! swung to cut av heel, as will he described, to engage a cam track 29, which is pivotally mounted at its ends on the frame of the machine. 'hen the ma- 9( chine is not actually cutting a heel, the arm 21 is pulled out to its central position as shown in Fig. 5, when the said cam track will engagv a flat surface 30 upon the under side of said arm 37.

The upper end of the shaft 24 has a former Ill fastened thereto which in the operation of the machine is adapted to engage guides 3'2 and 33, as hereinafter described. A frame-holder 31 is also fastened to the up- 100 per end of the shaft 524 and is slotted at 35 to receive a portion of a primary frame 36 which projects into said slot and is pivoted to-the frame-holder 34 at 37.

It will in seen that. the support 43 being fastened to the frame 36 in it screw 43, ditivrvnt supp rts may he nttarhed t0 said frame, of different. voni'um-s. ipngths and Widths and also of diiferrnt thicknesses as may he desired to actznn'unollate different shapes, sizes or heights of blocks and heels Wliifli are formed from Sfi fil blocks.

It will he imrlvrstoud that the primary franw 3G and the auxiliary frame 49 form tngether in effect a single frame and in some oftho claims the Word frame is used with this meaning.

The heel blank holding and clamping mechanism comprising the elements 36. 49, til, 46 is herein collectively designated by the term jack.

The general operation of the mechan sm hereinbefore specifically described is as followsz-A Wood heel blank 42 is placed upon the support 43 with the front edge of the blank corresponding to the breast of the finished heel abutting against the gage 44. At this time the handle 5! of the toggle lever 57 will be in its raised or dotted position, Fig. 1. The clamping member 53 and the links will also be in the dotted positions shown in Fig. l. and the primary clamping member will be raised to the dotted position illustrated in Fig. 1 by the spring 63. The blank having been placed in position, the handle 59 is now pushed downwardly from the dotted position to the full position illustrated in Fig. 1. thus causing the toggle links and their pivots and the pivot of. the tog 1e lever to be brought into alinenient wit each other and causing, the secondary clamping member 53 through the screw 55 to force the primary clamping member and its jaw 62 downwardly, thus firmly clamping the blank 42 in position against its support 43. At this time the longitudinal median plane B-B, Fig. 7, of the support 43 coincides with the longitudinal median plane A-A of the arm 21.

The operator then. by means of the handle 59, moves the support 43 and the parts supported thereon until the center lines A--A and B--B of the arm 21 and support 43 respectively assume the relative positions illustrated in Fig. 8 with the former 31 in engagement with the guide 32 and with one side of the blank in en agement with the cutter 16. the operator t en turns the support counter-cloclnvisc. the blank being held in engagement with the cutter 16 until the parts arrive in the position illustrated in 1g. 9. During these motions the former 31 is held against the guide 32 and the frame 36 is raised and lowered by means of the shaft 24, arm 27 and track 29 and is ti )ped upon its pivot 37 by means of the roll and cam-shaped track 69 in order to pro duce the proper shaped contour for the heel of the shoe on one side of the heel from the breast to the middle of the back of said heel. all in a manner well known to those skilled in this art.

The operator having finished one side of the heel now moves the parts to the position illustrated in Fig. it) which is the same as the position illustrated in Fig. i and then moves the parts until their center lines AA. and B-B assume the positions illustrated in Fig. 11 and finally to the positions illustrated in Fig. 1?. thus completing the forming of the heel. of the shoe.

The parts are then moved back to the position illustrated in Fig. 7 andthe tog le lever 57 thrown into the position illus trated in dotted lines, Fig. 1, thus releasing the heel and allowing to be removed by the operator or to drop lron'i the holder.

The COII'llJllHlllOll of the operating clamping functions in the lever 59 constitutes a. very important feature of the .rcsent invention. The operator is thus ena lied to turn one side of the heel, unjack it, and jack the new blank with successive movements of the same hand, without removal from the lever. The saving of time resulting from this construction is very important. It has been found that a very slow operator, with the machine of the present invention, can equal the production of a very fast operator who is using one of the old forms of jacks.
